Hop Sing was a semi-regular. It was also known to tackle social issues.Oh please, even TOS was far from artistic. It was a western set in space.
Since when is the "western" genre not a category of art?
Were there a lot of Russians and Asians and Blacks as featured ensemble characters in Bonanza?
Might have. Quint Asper, played by Burt Reynolds was a Native American.Did Gunsmoke feature an interracial kiss?
Did the Rifleman offer consistent subversive allegories about U.S. race relations and foreign policy?
I've no idea on that one.
Daniel Boone feature Native Americans (Mingo) and African Americans (Gabe) in its cast.
The High Chaparral featured several Hispanic characters. The Cannon and Montoya families were central to the show.
